Real condition

Situation 1: Sarah has lost her purse. She thinks that it can be at home. She's calling her mother.

Sarah: Mum, I think I've left my purse. Have you seen it?

Mum: No, but I'll look for it. If I find it I will call you.

In this example Mother considers it to be a real possibility so she says: If I find it I will call you.

This is the example of the First Conditional.

Situation 2: Steve, an advertising department chief, is talking to his managers about the role of commercials.

He says: If we have more commercials advertising this product we can attract more people and make them buy it.

In this example the situation is also real ‘ If we have more commercials advertising this product ’ and it can have possible results ‘ we can attract more people and make them buy it’.

This is the example of the ZERO CONDITIONAL.
